Rubbish. Unless you regularly write through transparent surfaces.Nope. My first instinct was to draw it as though I was seeing it on paper -- which on my face makes it backwards.
It actually takes hours of practice to be able to write backwards at speed with any true ability to even be consistently legible. Long ago the navy used transparent boards that enlisted personnel used to write reports on, but they wrote backwards. It took as much practice to do it well as typing does for most people. Muscle memorization and the natural inclination of a human to do it as they always do makes your hand naturally move as it has done thousands of times before, not as your "eye" sees it.
